|Combined Use of Rheometry and GPC/SEC for Characterising Ionic Polysaccharides|
John Duffy, Bernd Schaefer, Bert Postma
This poster shows how Rheometry and GPC can be complementary tools for characterising the behaviour of polysaccharides in solution
|Rate and Mechanistic Investigation of Eu(OTf)2-Mediated Reduction of Graphene Oxide at Room Temperature|
Tufan Ghosh, Sandeepan Maity and Edamana Prasad
Eu(OTf)2 has been introduced as an efficient reagent for the reduction of graphene oxide. Details kinetic studies have been performed which suggests that, the method is more efficient compared to that of other commonly used reduction methods.
|Electrical Fusion Machine - New electrical fusion system for x-ray fluorescence analysis|
Dr. Rainer Schramm, FLUXANA GmbH & Co. KG; Prof. Marie-Louise Klotz, Hochschule Rhein-Waal, Dr. Myint Myint Sein, Hochschule Rhein-Waal
This poster describes sample preparation in x-ray fluorescence analysis using the Electrical Fusion Machine by FLUXANA.
|Fluorescent Nanoprobes Confined in a Drop as a novel Sensing Platform for Detection of Metal Species at Trace Level|
Carlos Bendicho, Isabel Costas-Mora, Vanesa Romero, Isela Lavilla
In the last years, a great interest has arisen concerning the design and development of new optical probes for the sensitive and selective detection of chemical species making use of miniaturized and environmental friendly methods. In this sense, quantum dots (QDs) and metal nanoclusters (NCs) have important optical properties to be applied in analytical systems as fluorescent probes.
|Specificity of highly potent miRNA inhibitors|
Barbara Robertson, Andrew Dalby, Yuriy Fedorov, Jon Karpilow, Anastasia Khvorova1, Devin Leake, Annaleen Vermeulen
miRNA inhibitors are invaluable tools for elucidating the roles of miRNAs. However, potent inhibitors may also affect other miRNAs. To understand the potential cross-reactivity of miRNA inhibitors, various miRNA inhibitor designs were systematically tested. We demonstrate that mismatches both within and outside the seed region of the miRNA interfere with inhibition. Our findings indicate that features important for natural miRNA target recognition are also important for inhibitor specificity.
|Targeting Cancer Stem Cell-Related miRNAs for Prostate Cancer Therapy|
ANSHIKA NIKITA SINGH, MEGHNA BARUAH, NEETI SHARMA
The poster focuses on the pivotal function of miRNAs in tumorigenesis by regulation of self renewal and apoptosis via cancer stem cell signalling pathways with special focus on their regulation of Epithelial to Mesenchymal transition in metastatic prostate cancer.
|siRNA Screening: Development of Hit Stratification Strategies|
Žaklina Strezoska, Annaleen Vermeulen, Emily M. Anderson, Anja Smith, Devin Leake
This poster compares different approaches to hit stratification and validation after an initial screen. Standard siRNA reagents deconvoluted from a pooled set of four were compared to a pooled set of four specificity enhanced reagents. High confidence hits were similar. To explore the validity of low confidence hits, a chimeric approach was used whereby a gene-specific seed sequence was introduced into a non-targeting siRNA scaffold. This work resulted in new hit stratification strategies.
|Identification of microRNA targets using microRNA modulation techniques and gene expression arrays|
Emily M. Anderson, Maren Mayer, Kevin Sullivan, Barbara Robertson, Žaklina Strezoska, Annaleen Vermeulen, and Devin Leake
By examining the overlap of messages down-regulated by miRNA mimics and up-regulated by miRNA inhibitors, we robustly identify miRNA-regulated messages, many of which have canonical seed matches and some which are not identied by standard target prediction programs.
|Specificity and functionality of microRNA inhibitors|
Barbara Robertson, Andrew Dalby, Jon Karpilow, Anastasia Khvorova, Devin Leake and Annaleen Vermeulen
Our findings indicate that features important for natural miRNA target recognition also appear to be important for inhibitor specificity. Understanding the specificity of inhibitors allows for better interpretation of inhibitor activity in endogenous systems.
